AI Technical Summary

Benefits of technology

The gum base composition effectively degrades when exposed to sunlight and environmental conditions, reducing litter issues while maintaining the desired sensory and physical characteristics of chewing gum.

Problems solved by technology

Such gum litter is a nuisance, and its removal can be difficult and expensive.
However, the stickiness and elastic properties become undesirable when the chewed gum is discarded.
The incorporation of a plasticized proteinaceous material in chewing gum products, however, often compromises taste and thus can be undesirable from a consumer acceptability standpoint.
However, these gum products still do not solve the problem of discarded chewing gum cuds, which remain sticky enough to adhere to environmental surfaces and slow to degrade.

Proposed Testing for Degradation Properties of Example 1 and Comparison 1

[0113]The experiment described below can be carried out to evaluate photo-degradation properties of the gum bases.

[0114]Individual pieces of chewing gum products of Example 1 and Comparison 1 are placed in an Erweka DRT-1 chewing gum machine between two nylon nets. The gap between the jaws was set to 2.5 mm. The pieces are then chewed mechanically at 40 strokes per minute for 30 minutes in 20 milliliters of de-ionized water to form cuds.

[0115]Chewed gum cuds of Example 1 and Comparison 1 are left on an outdoor concrete slab for 7 days. The outdoor concrete slab receives direct sunlight. The outdoor concrete slab simulates the environmental conditions. The chewing gum cuds can be visually and physically examined at the end of the seven day period to evaluate respective photo-degradation properties.

[0116]In an embodiment, a photo-degradable gum base composition comprises an elastomer; and a block copolymer of vin...

Abstract

A photo-degradable chewing gum base composition including an elastomer; and a block copolymer of vinyl acetate and methylphenylsilane having a structure of formula (I)—wherein m and p are integers in the range of 1 to 500, and n is an integer in the range of 2 to 100, is disclosed. The block copolymer facilitates environmental degradation of improperly disposed chewing gum cuds. Also described is a method of preparing a photo-degradable chewing gum composition.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a U.S. national stage of application No. PCT / US2012 / 056003, filed on Sep. 19, 2012. Priority under 35 U.S.C. §119(a) and 35 U.S.C. §365(b) is claimed from U.S. Provisional Application No. 61 / 537,734 filed on Sep. 22, 2011, the disclosure of which is also incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Chewing gums generally contain a water-insoluble gum base, as well as sweeteners, natural or artificial flavors, and a variety of additives tailored to provide specific sensory and physical characteristics. The water-insoluble gum base provides the desired chewy and tacky properties to the chewing gum.[0003]Improperly disposed chewing gum cuds can adhere to the ground and other surfaces, where they are typically resistant to environmental degradation. Such gum litter is a nuisance, and its removal can be difficult and expensive.[0004]When a chewing gum is being chewed, it is desirable that the gum maintains its visc...
